In this paper, we construct a new signature scheme which is provably secure against adaptive chosen message attack in the standard model under the strong RSA assumption. The proposed scheme is different from Cramer-Shoup scheme and Camenisch-Lysyanskaya scheme and is more efficient than them. The tradeoff of the proposed scheme is a slight increase of the secret key.
